Hex Flange Sealing Nuts

ZAGO’s Hex Flange Sealing Nuts protect assemblies exposed to harsh environments, pressure and potential contaminants. While the flange acts as an integrated washer, each nut also integrates a custom-engineered, chemically resistant rubber O-ring that fits into a specially designed groove. Once installed, the O-ring compresses into the groove, forming a 360-degree barrier against water, humidity, oil, air, gas and dust upon installation.

Requiring no additional washers, gaskets or sealants, ZAGO’s Hex Flange Sealing Nuts provide improved protection with fewer parts, powering faster, more efficient assembly.

Ideal for use in hydraulic systems, medical devices, military and aerospace equipment, these nuts are customizable to withstand pressure, temperature and environmental extremes (see detail below).

ZAGO’s Hex Flange Sealing Nuts are engineered-to-order to ensure optimal performance. ZAGO’s team of US-based engineers is available to share their expertise and help make the best choice.
